Bond Length Definition: 

The equilibrium distance between the nuclei of two groups or atoms collaborating in a bond regarded as the bond length.

There are many things that can affect the bond length.

1)The dimension of the atoms. (The bigger the atoms, the better the bond length will be.)

There are many things that can affect the bond length.

1)The size of the atoms. (The bigger the atoms, the bigger the bond length will be.)

2) Hybridization

  • Number of bonds (More bonds means shorter the bond length)
  • Type of bonds (polar bonds shorter than non polar bonds)
  • More s-character means shorter the bond length.

Most of the cases, the longer the bond length, the easier it is to break apart those two molecules. (not solely bond length we have consider various things to break.)

EXAMPLE: The carbon-carbon on (C - C) bond length in diamond is 154 pm, which is also the biggest bond length that exists for ordinary carbon covalent bonds.

Bond Length is defined as the distance between the centres of two covalent bond atoms.

Bond length is related to bond order. If more electrons participate in forming a bond then the bond is shorter. It is also inversely related to bond strength  and the bond dissociation energy.

Bond length is measured in pico meters. Generally, it decreases across the row in the periodic table and increases down a group.
